 (a) the antenna specified on the licence; or

 (b) if no antenna is specified on the licence—an antenna that can be used in operating the station without causing harmful interference to a service provided by another station.

PART 3—CONDITIONS FOR FIXED LICENCE

(POINT TO MULTIPOINT STATION)

Conditions

 6. For paragraph 107 (1) (f) of the Act, every fixed licence (point to multipoint station) is subject to the conditions in this Part.

Restrictions on communications

 7. The licensee of a fixed licence (point to multipoint station) must operate a fixed station only to communicate with other stations to which the licence relates.

Supplementary base stations

 8. If the licensee operates a supplementary base station, the licensee:

 (a) must not operate the station if its operation causes harmful interference to a service provided by another station; and

 (b) must operate the station to transmit only using the receive or transmit frequencies specified on the licence for the base station; and

 (c) must operate the station only to overcome deficiencies within the coverage area of the base station; and

 (d) must not operate the station to extend the coverage area of the base station.

Remote stations

 9. (1) For a remote station, the licensee:

 (a) must not operate the station if its operation causes harmful interference to a service provided by another station; and

 (b) must operate the station to transmit to the base station or supplementary base station (if any) using the receive or transmit frequencies specified on the licence for the base station.

 (2) The licensee must not operate a remote station for data transmission, telecommand or telemetry if:

 (a) the duty cycle of the station is more than 1 in 30; or

 (b) the duration of a transmission from the station is more than 2 seconds; or

 (c) the minimum repetition interval of the station is less than 10 seconds.

 (3) If the licensee operates a remote station for data transmission, telecommand or telemetry in accordance with column 2 of an item in Schedule 2, the licensee must operate the station using the transmitter output power mentioned in column 3 of the item.

 (4) The licensee may operate a remote station for purposes other than data transmission, telecommand or telemetry if it is operated:

 (a) using the maximum transmitter output power specified on the licence; or

 (b) if no power is specified on the licence—using a maximum transmitter output power of 1 watt at the antenna input.

 (5) If a remote station is located in a central business district of a city or town, the licensee:

 (a) must not locate the antenna of the station more than 30 metres above the average surrounding ground level; and

 (b) must fit a device between the transmitter and the antenna that provides intermodulation performance equivalent to, or better than, the intermodulation performance achieved by an in line attenuation of 20 dB.

Remote control stations

 10. (1) If the licensee operates a remote control station, the licensee:

 (a) must not operate the station if its operation causes harmful interference to a service provided by another station; and

 (b) must operate the station to transmit to the base station or supplementary base station (if any) using the receive or transmit frequencies specified on the licence for the base station; and

 (c) must not operate the station unless it is operated using a maximum transmitter output power not exceeding 1 watt at the antenna input.

 (2) If the licensee operates a remote control station for data transmission, telecommand or telemetry, the licensee must operate the station using a transmitter output power that does not exceed the power necessary to achieve a wanted receive signal level of 10 dB above the input required to achieve a bit error ratio of 1 in 1000 at the base station.

 (3) If a remote control station is located in a central business district of a city or town, the licensee:

 (a) must not locate the antenna of the station more than 30 metres above the average surrounding ground level; and

 (b) must fit a device between the transmitter and the antenna that provides intermodulation performance equivalent to, or better than, the intermodulation performance achieved by an in line attenuation of 20 dB.

Short range communications

 11. (1) This section applies if a licensee of a fixed licence (point to multipoint station) operates a fixed station to communicate with another station not more than 100 metres from it.

 (2) The licensee must operate the fixed station:

 (a) in a manner that ensures that any transmitter or receiver conducted spurious power is less than minus 45 dBm; and

 (b) using an external antenna located not more than 10 metres above ground level; and

 (c) in a manner that ensures that the transmitter noise power does not exceed minus 60 dBm in a 10 kHz bandwidth at an offset that is at least 300 kHz from the frequency specified on the licence.

 (3) If the licensee operates the fixed station in a temperature range of 040 degrees centigrade (inclusive), the licensee must operate the station using adjacent channel power not exceeding minus 30 dBm in a 10 kHz bandwidth that is centred in the upper or lower 12.5 kHz channel adjoining the bandwidth specified on the licence.
